I know this topic may been be beaten to death already but I found something interesting.
I was doing some research about the Hands in the GKNOVA6.com site and stumbled on this... The image below is an extract from the STATION.SWF flash app that GKNOVA6 runs - not doctored in anyway except for the ZOOMed image.
Because the hands are clearly VECTOR graphics - not RASTER graphics like the background machines (Number Station Equipment) I thought Treyarch might have simply cut paste a hand from a NZ map. The power switch hand is much nastier than the hands in GKNOVA6.com so that theory is out *But* it does look like the RIGHT HAND is hacked off a body. Check out the image below.
